Comments for Days Supply Question for Liquid Medicine: 120ml, 10ml every 8 hours?

First, find the maximum the person can take per day: 10ml times 3 doses = 30ml max per day.

Then divide the total amount (120) by the max daily amount (30) and you get 4 days.

The days supply for this cough syrup is 4 days.

HOWEVER, some liquid cough syrup has maximum daily doses, for instance, Robitussin with Codeine has a maximum daily dose of 120mg (of the Codeine component).

When figuring days supply, remember that there may be ingredient/drug specific maximums that come into play here.

Another example is Tylenol. A person should not take more than 4,000mg or 4 grams per day. For the geriatric population, it may be closer to 3,000mg or 3 grams. When figuring days supply, these maximums need to be taken into account and factored into this calculation.

Thanks for the question!
